You go even further into the crowd analogy “So now think of going through a crowd in a group and over time the smaller faster people end up ahead and together compared to the larger slower people.”
You watch your family as it almost looks like they’re following. “Okay, but this only works in something like water for diffusion, so that would be like traveling in the crowd only on the sidewalk”
Your mom looked a little confused and chimed in, “I don’t get it water? shouldn’t these particles always move in all directions, and I just don’t see what this has to do with colors?”
“Different particles make different colors,” you reply
“Always? What if someone dyes it, what would ya do then?”
“Mom, no one’s going to dye our compounds”
“I’m just saying, I’d watch out for that.”
It didn’t seem like you were selling anyone on your research, what do you do?
